pplication filed November 22, 1916. Serial No. 132,748.

Be it .known that I` lVlLmaw LENNoN, a citizen of the lvnited States, residing at Manitou, county of El laso, and State of Colorado, have invented certain new and ,useful Improvements in Vaporizers for Internal-(`ombustio El fines; and I do declare the following tri-be a full, clear, and

4exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanyingr drawings, and to the characters of reference marked tl1ereon,-.`which forln a part of this specification. A

My invention relates to improvements in means for more completely vaporizingr the motive fluid or other substances on their way to the intake of the engine and for introducingr hot moistair or vapor of water thereto `in order to prmluce a readily ignitij ble explosive mixture which shall also be of such character that the combustion within the engine cylinders shall be practically per. fect, thus avoiding the accumulation of carbon or unburncd fuel within the engine cylindcrs.

ln myimprovement I arrange a chamber `into which thc motive fluid or substance is delivered on its way to the intake of the engine, in such a manner `that this chamber shall be surrminding or inclosed by a jacket through which the exhaust material or burnt products of combustion pass as they leave the exhr st manifold or pipe. I also pro' vide means for exhaustingthe air from said jacket when the engine is not running, thus producing a vacuum in the said jacket, which will have a tendency to maintain the heat within the chamber, which condition will facilitate' the starting of the engine.

Provision is also made for mingling v apor of water with thervaporized motive fluid,

nate the engine considered in its entirety and ,equipped with an intake manifold G; a carburetor T; and an exhaust manifold 8f"- A pipe leads from a source of liuid supply (not shown) to the carburctcr. This pipe is equipped with ay valve lll whose casing is also in communication with one extremity of a pipe. 12, the opposite extremity of said pipe communicating with a small chamber 13 from which also leads a pipe 14;, to a mixing chamber 15 which is in communication at one extremity as shown at 16 with the intake manifold, while its opposite ex trcmityis equipped with a closable valve 17 which is pivotally connected as shown at 18 with the inner extremity of a rod 15') whose outer extremity 2() passes through and is movable in the footboard orrlash E21 of the automobile. The chamber 13 is surrounded by afjacketz which may be filled with any suitable. material 23 as santi which will haven ay tendency to maintain and equalize the tem perature within the chamber 13. Surround ing the jacket E22 another jacket 24; which in reality forms a part of the exhaust manifold. since the products of combustion leaving the exhaust manifold pass through the chamber of' jacket 2l and thus heat the chamber 13 and also the jacket 22. Two 85, valves 25 and 2G arranged within the exhauat manifold on opposite sides of the jacket 24. may be closed as indicated in full lines ini the drawing. In tliis event the en gine cxhausta through an outlet 4-1. Under thesev conditions the jacket trnay` be exhausted of its air by .;on"hecting the Isame with an cxhauster o air pump of any suitable character. As illustrated in the draw ing` a conduit E27 colmiiunicates with the jacket 24 at one extremity, while its opposieV `aite extremity is in communication with an air pump 28 which is operated from the shaft Q!) of the engine through the medium of an operative connection as a belt 30 and pulleys 431. and 32. ll'hen the valves 25 and 26 are opened in order to allow the exhaust or products of combustion to escape thpough thewjacket-Qt, the exhaust outlet Il will he closed bythe valve A as indicated hy dotted lines in the drawing.

Ae illustrated in the drawing, t-he sti-ucture is provided with a wate receptacle. 33 which is in `communication ley means'of a, pipe ill with a receptacle mounted di rectly on the exhaust manifold 8. The pipe :itis provided with a controlling valre 3Q means or" a rod 537 Whose reareXt-remity is accessible to the chaufi'eur. It should be eX- plained that each of the 1Jalve pieces 25 and 26, isconnected with an operatingv rod 3S,

' these rods passing through openings formed in the dashboard and being' slidable therein. By properly adjusting` the Valve 36, the Water 'fromthe tank 33 maybe admitted into the receptacle 35 in which itis vaporized by virtue of the heated condition of the receptacle due to its position on the exhaust manifold or pipe. This vapor of. water passes through a. chamber liwhere it miiigles with the motive fluid to form a highly combustible eX- plosive mixture, the same bein of such character as to be readily igniti le Within the engine cylindersand to result inproctically perfect combustion.

From the foregoing description the. use and operation of my improvement will be readily understood. ln the first instance or when starting the machine, the motive iluid passes directly Jfrom the supply pipe 9 to the carbureter 7, and this continues until the engine is well started, after which the valve 10 may be adjusted through the medium of a rod 40, to switch the motive fiuid from the pipe 9 into the pipe 12, whence it passes into the chamber 13, and thence through the pipe 14. to the mixing chamber 15 Where it mingles with the Vapor of Water which passes to the mixing chamber through the pipe 39 which isv in communication with the vaporizing receptacle 35 mounted on the exhaust manifold or pipe as heretofore explained.

By yirtue of the fact that the mixing chamber 15 is' provided with an open eid controlledhy the valve 17, it becomes prac ticable if desirable, to permit the entrance of atmospheric airto the mixing chamber in conjunction and to mingle With-the vaporized motive fluid and vapor of water which are introduced tosaid chamber, as heretofore explained.
